Q:Alkali soda water
Soda water is an aqueous solution of sodium bicarbonate, containing weakly alkaline, medical topical disinfectant, drinking and neutralizing the body's acid-base balance, changing the acidic constitution. Most of the soda water sold on the market is a synthetic carbonated beverage that is compressed into purified water and added sweeteners and fragrances. Soda water is a carbonated beverage, is pressed into purified drinking water into carbon dioxide, and add sweeteners and spices. He is an aqueous solution of sodium bicarbonate, containing weakly alkaline, medical topical sterilization, oral administration can be integrated within the body's acid-base balance, change the acidic body. Sodium bicarbonate is what we say baking soda molecular formula NaHCO3 is usually said that the surface screwdriver, but this is not directly joined the surface screwdriver, the market selling soda water is mostly in the purified drinking water into the carbon dioxide, and add Sweeteners and fragrances of synthetic synthetic carbonated beverages. Baking soda: NA2CO3 soda: NAHCO3, weak base. Medical topical disinfection can be sterilization, oral administration can cure too much acid. Soda water is actually carbonated water Well, Coke, whiskey what is inside. Pure soda water also has, usually the equipment, supermarkets have to sell. Can be used for cocktails. Can go to the pharmacy to buy small soda tablets with warm water to the system, but the concentration is not good to master.
Q:How to see the whole bread of the alkali alkali small
Sniffing Such as the smell of the dough, indicating that the alkali is placed properly. (4) catch. Hand dough, such as dough sinking, inelastic, that the alkali put more; if not sticky, nor sink, and there is a certain flexibility, that alkali is just right. (5) taste. Will be rubbing the base of the dough to pull a little bit into the mouth taste, if the sour that alkali less; if the alkali astringent taste, that the alkali put more; if you feel sweet, that is, alkali is appropriate The
Q:The commonality of the base
alkali and acid reaction, the formation of salt and water (such reactions are commonly referred to as neutralization reaction)
Q:What is the role of alkaline powder
In addition to medicinal function, alkaline powder also has a strong decontamination function. I brought a cup full of dirt, rinse with water, and then rubbed and rubbed by hand, but the dirt or tightly stick the cup. I add detergent, but also hard to rub, or stubborn dirt still still motionless. I sprinkled with alkaline powder, rubbing the side of the water gently rubbing the cup, those dirt seems to be afraid of alkaline powder like all fled, and soon the cup becomes smooth as new!
Q:What is alkali active aggregate?
In the construction process sometimes encounter the following questions: What is the alkali active aggregate? How does it determine that the aggregate is an alkali-active aggregate? Before answering this question, let's say what is the alkali-aggregate reaction. The alkali-aggregate reaction refers to the soluble alkali (K) in the cement, admixture, admixture or mixed water *, Na *) is dissolved in the concrete void fluid and reacts with the active ingredient (such as SiO2) with the alkali in the aggregate after the coagulation and hardening of the concrete, resulting in alkali-containing gel, water swelling, Internal stress and cracking. It can make a serious decline in the durability of concrete. It is difficult to prevent its development, it is difficult to repair.
Q:Would you like some rice when you cooked rice or millet gruel?
Sometimes some people in the cooking boiled rice gruel, grasp some of the alkali on the porridge, the big canteen chef especially like to do so. On the one hand figure cooked fast, on the other hand add alkali after cooking porridge more sticky delicious, taste and good. However, they do not know that this is to destroy the rice (rice, millet) in the most valuable nutrients, such as vitamin B1 and vitamin B2. And because vitamin B1 is known as the spirit of nutrients, the nerve tissue and mental state has a very important impact, lack of fatigue, forgetfulness, anxiety and other symptoms, so boiled millet gruel must not add alkali.
Q:What is the use of alkali?
Edible alkali has a small amount of fermentation, but its greatest role is to fermented the surface to the acid
Q:What is alkali sand
Potassium carbonate, white crystalline powder. Density of 2.428g / cm3. The melting point of 891 ° C, the decomposition of boiling point, the relative molecular weight of 138.21. Soluble in water, aqueous solution is alkaline, insoluble in ethanol, acetone and ether. Hygroscopicity, exposure to air can absorb carbon dioxide and moisture, into potassium bicarbonate, should be sealed packaging. Hydrates have a water, dihydrate, sour things. Potassium carbonate aqueous solution is alkaline. Insoluble in ethanol and ether.
Q:Is the plant base a food base?
(Sodium bicarbonate) (chemical formula Na2CO3) and baking soda (sodium bicarbonate) (chemical formula NaHCO3), baking soda is a solution of soda ash or crystal absorption after the carbon dioxide Of the finished product, the two are essentially no difference. Therefore, edible alkali in some places also known as baking soda (powder). Edible alkali is solid state, round, color white, soluble in water. Alcohol is not a commonly used condiment, it is just a food loose agent and meat tenderener, can make dry goods raw materials quickly rise, soften the fiber, remove the dough's sour taste, the appropriate use can bring excellent food The color, smell, taste, shape, to enhance people's appetite. Alkaline used in a large number of food processing such as noodles, bread, bread and so on.
Q:What is the important character of Chinese made alkali?
(1) NH3 + H2O + CO2 = NH4HCO3 (2) NH4HCO3 + NaCl = NH4Cl + NaHCO3 ↓ (3) 2NaHCO3 (heating) = Na2CO3 + H2O + CO2 ↑ That is: ① NaCl (saturated) + NH3 + H2O + CO2 = NH4Cl + NaHCO3 ↓ ②2NaHCO3 = Heating = Na2CO3 + H2O + CO2 ↑ Ammonia reacts with water and carbon dioxide to form a molecule of ammonium bicarbonate, which is the first step. The second step is: ammonium bicarbonate reacts with sodium chloride to form a molecule of ammonium chloride and sodium bicarbonate precipitation, sodium carbonate is precipitated because it is less soluble.
